AUTOMATIC DUMPINGI-BAILER FOR DEEP WEL/LS.

SPECIFEOATION forming part of Letters Patent No. 650,317, dated May' 22, 1900. Application filed August 3l, 1899. Serial No. 729,115. (No model.)

To all whom, it may conccraj Beit known that I, EDWIN A. HARDIsoN, re siding at Santa Paula, in the county of Ventura and State of California, have invented a new and useful Automatic Dumping-Bailer for Deep W'ells, of which the following is a specification.

The object of my invention is to provide a sim ple and elective appliance for introducing water into the bottom of a well which is being drilled without allowing the water to come into contact with the walls above the bottom of the well-that is to say, it frequently occurs in drilling a well that a stratum of earth is drilled through, which is liable to cave if wet, and in such cases when water from the surface is let into the well to. wet the bottom of the well, so that the drill will Work, such water by running down the wall above the bottom of the Well will often cause it to cave. With my invention the Water can be readily lowered to the bottom of the well and there automatically discharged, and the bailer can then be drawn out of the well without withdrawing the water.

My invention works automatically, so that the water can be thus put into the bottom of the well at any depth. This makes my dumping-bailer of special value for deep wells.

The accompanying drawings illustrate my invention.

Figure l is a mid-section of my newly-inl vented dumping-bailer with the valve closed ready to lower water into the well. Fig. 2 shows the bailer with the valve open to dump the water. In Figs. l and 2 the valve and lower part of the valve-rod are shown intact. Fig. 3 is a plan view of the bailer with parts in position shown in Fig. 2.

A indicates the shell or bucket of the bailer,

provided near its bottom with a valve-ring a,

having a hole ct' therethrough for the va1verod and provided at the top with a valve-rod guide, being the bucket-bail a, which has a hole Ct" therethrough for the valve-rod to play up and down in. i

B indicates the valve-rod, provided at its lower end with a ball-valve b to close the opening ct in the valve-ring. The valve-rod exgravity, thus opening the hole through the tends upward through the hole in the Valve# ring and through the guide-hole ct" in the bail.

C indicates an automatic latch pivoted to the valvesrod B to playin the valve-rodguide' hole ct" and adapted to latch under the catch formed by the bail a when the valve is open.

D indicates a latch-spring arranged to nor# mally hold the latch in its latching position to lift the shell.

l indicates the handle of the latch. l

2 indicates the body of the latch which is narrow enough to play up and down in the hole tt'". It ispreferably chamber'ed in a chamber b in the valve-rod B.

3 indicates a finger or' lug projecting upward from the body 2 of the latch to engage a stop b in the valve-rod to stop the latch in its locking position. c

E indicates the hoisting-rope, which is fas- .tened to the valve-rod B.

In practice when it is desired to lower water into the well the latchC is thrown iuto the position indicated in Fig. 1 to allowit to pass up through the hole a" inthe bail. Then the device being suspended by the rope E the shell or bucket A will drop down along the valve-rod B until the ring ct rests on the valveball b, thus closing the hole ct' in the valvering. Then the bucket is filled With Water and is lowered into the well until it reaches the bottom ot' the hole and is stopped there- Then the valve-rod B will descend by valve-ring and bringing the body2 of the latch C underneath the bail et". Then the dumpingbailer is drawn up and the water Hows down through the hole a and out through the holes 4 in the bottom'of the bucket or shell and is thus discharged at the bottom of the well. The bailer is then drawn out of the Well empty.

5 indicates a stop on the valve-rod to engage the bail to prevent the valve-rod from going down too far.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A dumping-bailer comprising a shell proa vided near its bottom With a valve-ring and and to latch under the catch to sustain the d" provided at the top with a, rod-guide and with shell with the valve open.

a catch; a Valve-rod extending through the Y hole in the ring and through the guide, and EDWIN A HARDISON' 5 provided at its bottom with a, Valve to close Witnesses:

Jthe hole in the valve-ring; and a latch pivoted JAMES R. TOWNSEND, to the Valve-rod to play through the guide l FRANCIS M. TOWNSEND.
